FIG. 1 is a schematic diagram showing a conventional housing structure;
FIG. 2 is a cutaway diagram showing part of a conventional housing structure;
FIG. 3 is a schematic diagram showing a housing structure in a preferred embodiment of the invention; and
FIG. 4 is a cutaway diagram showing part of a housing structure in a preferred embodiment of the invention.
 DETAILED DESCRIPTION OF THE EMBODIMENTS
Please refer to FIG. 3, and a housing structure 100 of the invention can be applied to common electronic products such as mobile phones, personal digital assistants or electronic dictionaries, etc. The housing structure 100 in a preferred embodiment of the invention includes an upper housing 110, a lower housing 120, a first waterproof member 130, a plurality of second waterproof members 140 and a plurality of locking members 150. When the upper housing 110 is combined with the lower housing 120, a seamless space S can be formed in the interior of the housing structure 100 and is used to hold precision electronic components. Liquid and water vapor are fully prevented from entering into the seamless space S because of the first waterproof member 130 and the second waterproof member 140, so that the electronic components are prevented from being affected with damp.
FIG. 4 is a cutaway diagram showing part of the housing structure 100 when the housing structure 100 is locked. Wherein the upper housing 110 includes a first connecting portion 111 having a first outer edge 111C, a through hole 111H and a first recess N1. The lower housing 120 includes a second connecting portion 121 having a second outer edge 121C, a locking portion 121N and a first recess N1. The first recess N1 of the first connecting portion 111 and the first recess N1 of the second connecting portion 121 are correspondingly formed. The first waterproof member 130 is protrudently disposed in the first recess N1 of the first connecting portion 111 or the second connecting portion 121.
When the housing structure 100 is locked, the locking member 150 passes through the through hole 111H from the upper housing 110 and is locked with the locking portion 121N of the lower housing 120 to fix the upper housing 110 and the lower housing 120. The first waterproof member 130 made of rubber is tightly held between the first recesses N1 of the upper housing 110 and the lower housing 120. Simultaneously, the first outer edge 111C of the upper housing 110 and the second outer edge 121C of the lower housing 120 contact with each other, and a seamless space S is formed in the interior of the housing structure 100. In the embodiment, the first waterproof member 130 is not integrally formed with the through hole 111H or the locking portion 121N. Although the locking portion 150 still has an axial downward pressure because of the locking, the pressure cannot pull the first waterproof member 130 to cause deformity of the first waterproof member 130, and then water vapor cannot infiltrate.
To achieve the objective of further strict waterproofing, the first connecting portion 111 and the second connecting portion 121 further have a second recess N2 circularly formed at the periphery of the through hole 111H, and the second waterproof member 140 is protrudently disposed in the second recess N2. When the locking member 150 passes through the through hole 111H to be locked with the locking portion 121N, the second waterproof members 140 are tightly held between the upper housing 110 and the lower housing 120.
In the embodiment, the second waterproof member 140 can be a circular rubber gasket and is disposed in the second recess N2. The second waterproof member 140 is made of rubber and can be tightly fit with the upper housing 110 and the lower housing 120. When the upper housing 110 is combined with the lower housing 120, the above second recess N2 can be omitted, or only one of the first connecting portion 111 and the second connecting portion 121 needs to have the second recess N2. In addition, the number of the above second waterproof members 140 is corresponding to that of the through hole 111H and the locking portion 121N and is not limited.
The second waterproof member 140 in the embodiment is also independently disposed around the through hole 111H and is not integrally formed with the first waterproof member 130. As a result, when the locking member 150 presses downward along an axis, the waterproof function of the first waterproof member 130 cannot be affected. Water vapor is prevented from infiltrating into the electronic device 100 from the neighborhood of the first waterproof member 130 deformed because of the pull. The second waterproof member 140 disposed around the through hole 111H can further bring a waterproof function into play. The water vapor is prevented from entering into the seamless space S from thin apertures between the locking member 150 and the through hole 111H.
Compared with a conventional housing having an integrally formed waterproof member, a distance G is formed between the first waterproof member 130 and the second waterproof member 140 in the invention. That is, the first waterproof member 130 and the second waterproof member 140 are independent components, so that when the locking member 150 is locked with the locking portion 121N. Pressure is only exerted on the second waterproof member 140, and the first waterproof member 130 is not affected and deformed. Then the objective of fully waterproofing is further effectively achieved.
Although the present invention has been described in considerable detail with reference to certain preferred embodiments thereof, the disclosure is not for limiting the scope of the invention. Persons having ordinary skill in the art may make various modifications and changes without departing from the scope and spirit of the invention. Therefore, the scope of the appended claims should not be limited to the description of the preferred embodiments described above.
